I have had issues with Bluetooth ever since iOS 14, Bluetooth actually got better with iOS 14.3 for me, but iOS 14.4 seems to have reversed whatever it was that solved my issues, now with iOS 14.4 I am having more issues with Bluetooth than I ever have before with any iPhone or iOS. Same things as reported, doesn’t connect to car stereo without fiddling in settings, turning off/on Bluetooth, hard rebooting iPhone. My iPhone used to also pair flawlessly with my Windows 10 laptop for dynamic lock, now it doesn’t always see the phone without the same fiddling around and hard rebooting, even when it does connect, it drops out within 30 minutes tops and requires the fiddling in settings and hard rebooting to fix it (temporarily)...
